Satiety

Satiety is a feeling of fullness and satisfaction after eating. It is the
opposite of hunger or appetite. The mechanisms and events that lead to a
state of satiety are numerous, complex, and not well understood. It is
believed that the release of certain
hormones
and the firing of certain nerves when food enters the intestine sends
messages to the brain to signal that it is time to stop eating.
Genetic
predisposition and
learned behaviors
may affect at what point satiety occurs in an individual. Learning to
stop eating when satiety is reached is an important component of weight
control.
